Abstract

There is provided according to some embodiments of the invention a wireless identification device (‘WIDD’) with tamper protection. According to some embodiments of the invention, the WIDD may include a tamper protection sensor and a processing module. The tamper protection sensor may be configured for sensing a physical property related to at least one essential functional component of the WIDD, the physical property is affected by an attempt to physically remove the at least one essential functional component of the WIDD from a surface to which it is attached during initialization. The processing module is adapted to receive or obtain, at a substantially high frequency, data corresponding to readings from the tamper protection sensor. The processing module is responsive to a relatively sharp and abrupt non-transient change in the level of the physical property for initiating a disablement action or procedure.

Claims

1-6. -6. (canceled)

7. A wireless identification device (“

WIDD”

) with tamper protection, comprising;

a. a transceiver;

b. an antenna operatively connected to the transceiver through wires passing through a hole within a substantially solid surface, the hole is small enough to prevent the passage therethrough of either the antenna or the transceiver;

c. a processor adapted to detect a relatively sharp and abrupt non-transient change in the level of the inductance of the antenna which corresponds to a severing of the wires connected to the antenna and the processor is responsive to the change for initiating a disablement action or procedure.

8. The device according to claim 7, wherein the antenna is a ring type antenna.

9. The device according to claim 7, wherein the antenna is fitted around a metallic fuel inlet.

10. The device according to claim 7, wherein the processor is responsive to the rate of change of the inductor'"'"'s inductance.

11. The device according to claim 10, wherein the processor is responsive to any drop, at any rate, in the amount of inductance of the inductor below a predefined threshold for initiating the disablement action or procedure.

12. The WIDD according to claim 7 further comprising:

a. a storage module adapted to substantially permanently store transaction enabling data in the WIDD;

b. communication module adapted to receive incoming signals and/or to transmit signals to external components of an automatic transaction system, the communication module including the transceiver and is associated with an antenna;

c. a power source for powering components of the WIDD.

13. A wireless identification device (“

WIDD”

) with tamper protection, comprising;

a. an inductor attachable to or in a vicinity of a metal surface, a contact or a proximity of the inductor to the metal surface significantly affecting its inductance;

b. a tamper protection sensor adapted to measure the inductor'"'"'s inductance;

c. a processing module operatively connected to the tamper protection sensor, the processing module is responsive to a relatively sharp and abrupt non-transient change in the inductor'"'"'s inductance level, the change corresponding to a removal of the inductor from the vicinity of the metal surface for initiating a disablement action or procedure.

14. The device according to claim 13, wherein the inductor is an antenna that is additionally used for facilitating communication to and from the WIDD.

15. The device according to claim 14, wherein the antenna is a ring type antenna.

16. The device according to claim 14, wherein the antenna is placed within a casing of the WIDD, the casing is attached to a metallic surface and the antenna is secured to an area of the casing that is relatively close to the metallic surface.

17. The device according to claim 14, wherein the antenna is external to a casing of the WIDD within which other functional components of the WIDD are located.

18. The device according to claim 14, wherein said device further comprises a transceiver and the antenna is physically removed from the transceiver and/or from the tamper protection sensor and is connected to the transceiver through wires.

19. The device according to claim 14, wherein the antenna is fitted around a metallic fuel inlet.

20. The device according to claim 13, wherein the processor is responsive to the rate of change of the inductor'"'"'s inductance.

21. The device according to claim 20, wherein the processor is responsive to any drop, at any rate, in the amount of inductance of the inductor below a predefined threshold for initiating the disablement action or procedure.

22. The device according to claim 13, wherein the inductor is a dedicated inductor, and wherein the dedicated inductor is coupled to an essential component of the WIDD which is intended to remain in the vicinity of a metal surface, so that removing the essential component from the metal surface causes the inductance of the inductor coupled thereto to be significantly affected.

23. The WIDD according to claim 13, further comprising:

a. a storage module adapted to substantially permanently store transaction enabling data in the WIDD;

b. communication module adapted to receive incoming signals and/or to transmit signals to external components of an automatic transaction system, the communication module including a transceiver and is associated with an antenna;

c. a power source for powering components of the WIDD.
